Slit-Type Coating Machine

The slot die Coater forms a coating chamber through two opposing gaps, and the coating material is pumped and extruded from the slot to create a uniform wet film. It is used for quantitative coating on substrates such as paper and films, enabling the preparation of functional coatings.
Selection
Match the coating head size based on the substrate width, select the pumping system according to the coating viscosity, determine the gap adjustment precision in combination with the production speed, and consider corrosion-resistant materials to accommodate different solvent-based or water-based coatings.
